For Higher Physics, revise how to calculate the expected direction of refracted rays using Snell’s law. Calculate critical angle given refractive index.

Few people today would dispute that the use of Mie Theory provides the only route to accurate particle size analysis when measuring fine particles using laser diffraction. The international standard ...

Ray trace parameters were used to calculate the refractive index distributions for 633 nm light in all 17 lenses and for 532 nm light in 10 lenses.

A second-moment turbulence closure model is used to investigate the make-up of the refractive structure parameter Cn2 for acoustic, optical and microwave radiation. For these different forms of ...
